This document is the Smoothwall Sewer & Drain Pipe Specification. Scope, pipe requirements, joint performance, material properties and installation explained.

This specification describes ADS Smoothwall Sewer & Drain pipe in 3- and 4-inch (75 and 100 mm) diameters for use in gravity flow drainage and leach field applications.

ADS Smoothwall Sewer & Drain pipe shall have a smooth interior and exterior. 3- and 4-inch (75 and 100 mm) pipe shall meet the requirements of ASTM F810. Manning's "n" value for use in design shall not be less than 0.009.

Pipe joints shall be bell-and-spigot. Bell ends shall be integrally formed on the pipe at one end to form a soil-tight connection.

Pipe material shall be high-density polyethylene conforming with the minimum requirements of cell classifications 424410C or E as defined and described in the latest version of ASTM D3350. The material formulation shall include recycled polyethylene.

For gravity-flow drainage applications, installation shall be in accordance with ASTM D2321 and ADS recommended installation guidelines with the exception that minimum cover in traffic areas shall be one foot (0.3 m). For leachfield applications, installation shall be in accordance with ASTM F481 and as regulated by regional, state, and local agencies. Proper authorization for specific applications and designs should be obtained prior to installation to ensure suitability in certain locales.

Figures showing a white skin/black core pipe, bell end and spigot is included with a perforation options chart and 3 perforation options diagrams.
